3D-Tech News Around The Web / ATI RV740 GPU and Architecture Analysis
« on: September 28, 2009, 10:39:45 AM »


The HD 5870 already measures in at an unheard of 11″ long, bigger than what a lot of case manufacturer’s have budgeted for (standard spacing is 10.5″).  Images obtained this morning seem to depict that the x2 version could be even bigger!

While it is difficult to get an accurate length just from pictures, with a second die , it would be nearly impossible to squeeze it into the same sized PCB as the 5870. From our basic visual calculations, the card appears to be extended by at least 1″ – 1.5″, giving it a total footprint of an estimated 12″-12.5 inches long. Best of luck fitting this behemoth into any mid sized tower, or even a smaller full tower.


This multi-GPU beast more appropriately known as Radeon HD 5870 X2 was shown in a meeting room running CryTek’s latest CryEngine 3 development build at very smooth framerates. More specifically, the engine was running at 1920x1200 with AA turned off (as CryEngine has never needed manual AA) and the Screen Space Ambient Occlusion (SSAO) rendering technique was significantly more pronounced than in Crysis and Crysis Warhead.

3D-Tech News Around The Web / AMD Demos Dual Cypress Graphics Card - Hemlock
« on: September 28, 2009, 07:06:25 AM »

While the enthusiasts are getting crazy over the Radeon HD 5870 and Radeon HD 5850 cards, AMD keeps up the hype by showcasing us a machine fitted with a Hemlock graphics card. Due to launch later this year in Nov-Dec, a Hemlock card has two "Cypress" ASICs on it and it is priced below US$500.

3D-Tech News Around The Web / Sapphire Radeon HD 5870 1GB in CrossFire
« on: September 24, 2009, 08:00:53 PM »

We're not going to blabber on too much here, because we're sure you don't want to read about us having two HD 5870s. You just want to know what happens when we put those two HD 5870s into the one system and run our flurry of benchmarks.


We loved the HD 5870 in single form and we love it even more now. CrossFire manages to scale extremely well and if this is an idea of what we can be expecting from the HD 5870 X2, then NVIDIA had better be worried! Once companies like Sapphire start attacking the model with new cooling and overclocks, it's only going to get better for the model.

3D-Tech News Around The Web / Larrabee: first public demonstration
« on: September 23, 2009, 10:11:14 AM »

Intel has given the first ever public demonstration of its long-awaited Larrabee graphics system.

"Larrabee gives you a fully programmable rendering pipeline. So you can use DirectX, or OpenGL - or your own pipeline."

"These reflections here are just ten lines of code," he stated. "To do something like this on a conventional GPU would be really quite painful."


Developed by LucidLogix and dubbed HYDRA, the technology was set to revolutionise multi-GPU graphics by eliminating the need for specific, limited driver support from either ATI or NVIDIA in the form of CrossFireX or SLI, respectively. Rather, sitting in-between the DirectX API and graphics cards, Lucid employed a manufacturer-agnostic chip and associated software that latched on to the PCIe bus to mete out the necessary data to two-, three-, and four-card combinations.

So, a year or so later, LucidLogix is back with a newer HYDRA 200 chip. This time around, however, the company has leveraged the support of a tier-one motherboard vendor, and we'll be seeing the HYDRA-powered board in a few weeks' time.

There are several key features in DirectX 11 that will make graphics on the screen look closer to reality. Tessellation is used to increase the polygon count in an image. The more polygons, the more realistic the image will look. Gone will be the days of blocky looking characters as the polygon count will increase significantly with the next generation of DirectX 11 hardware.

Multithreaded rendering will allow Direct3D processes to run across multiple CPU cores. Most games are using dual core CPUs, but multithreaded rendering will make gaming on triple and quad cores finally worth the cost. A faster processing pipeline and increased scaling are only some of the benefits.

DirectCompute allows access to the shader cores and pipeline. It allows for non-proprietary physics implementations, which some open-source physics projects are looking to take advantage of. Video transcoding will also take a significant leap due to access to the many processors on a modern GPU.

3D-Tech News Around The Web / Pixelux team up with AMD on OpenCL
« on: September 17, 2009, 02:18:31 PM »

As far as AMD+Pixelux announcement go, there isn't exactly much to be discussed - Pixelux will work closely with AMD in order to push OpenCL CPU+GPU acceleration of its Digital Molecular Matter Engine, and the platform of choice is AMD Opteron with ATI Radeon 5800 series and FirePro graphics cards.

3D-Tech News Around The Web / VSXu Audio Visualizer
« on: September 13, 2009, 04:29:09 PM »

VSXu is a free to use program that lets you create and perform real-time audio visual presets. VSXu is currently available for Windows XP (32-bit) & GNU/Linux requires OpenGL 2.0-compatible card. VSXu is free to use and distributable under a GNU GPL v2 license.

VSXu uses OpenGL for audio visualization.

3D-Tech News Around The Web / Pixel Bender
« on: September 13, 2009, 04:26:17 PM »

The Adobe Pixel Bendertechnology delivers a common image and video processing infrastructure which provides automatic runtime optimization on heterogeneous hardware. You can use the Pixel Bender kernel language to implement image processing algorithms (filters or effects) in a hardware-independent manner.  The Pixel Bender graph language is an XML-based language for combining individual pixel-processing operations (kernels) into more complex Pixel Bender filters.

Virtual visit to the newest Vizerra 3D Model – Prague’s Old Town Square.


I already talked about Vizerra in this post:


The SAPPHIRE Vapor-X Radeon HD 4890 2GB GDDR5 PCI Express 2.0 video card is one of the fastest single slot graphics cards on the market today. This versatile and powerful card has 2GB of high-performance GDDR5 memory running at 1050MHz, while the core operates at 870MHz. Read on to see how this factory overclocked card does on out 30" display.

Atangeo Balancer is a tool to optimize and simplify 3D models. Its exceptional performance and a novel user interface allow finding perfect balance between visual appearance and the number of polygons, quickly and easily. Balancer utilizes a high quality polygon reduction (aka mesh simplification or decimation) to preserve the visual appearance of your model. The model features, normals, texture coordinates, layer boundaries are all honored by Balancer. It can optimize your models even further to dramatically speed up rendering of your models. Balancer features a fast and efficient triangle reordering that can be tuned for various rendering methods like triangle strips and array/buffer based rendering. Balancer Lite is a free version. It is fully functional but works with small meshes only. The limits for a single mesh are 15000 triangles and 10000 vertices.

3D-Tech News Around The Web / Asus MARS Quad SLI - Extreme Gaming
« on: August 27, 2009, 06:14:15 PM »

With Nvidia not going ahead with an enhanced GTX295 ASUS have decided to do so themselves and the result of this venture is their MARS card. In addition to cores which are higher specification than the standard GTX295 Asus have also pushed the cards as far as they can go in terms of memory support with each GPU having access to 2 GB of GDDR3... that’s 4 GB per MARS card, more than enough to make enthusiasts and benchmark junkies drool with excitement.

So today we see how much of an improvement the MARS card is over a standard GTX 295 but we won’t stop there... we will also pair two of these cards in SLI to create a configuration which is essentially the same as GTX 285 Quad SLI. Asus have basically rewritten the Nvidia rulebook – so today we find out if this incredible engineering creates a card that is significantly better than anything else currently available.
